Research On The Model Of Workflow Instance And Scheduling Based On Industry And Commerce Cooperative Platform

As a platform for information integration,the industrial and commercial collaborative platform can conduct industrial and commercial business transactions,at the same time penetrate the supply chain,solve the problem of internal information interoperability between industrial and commercial systems,realize information sharing between industrial production,commercial sales,purchase and sale,Meet a series of requirements include the business-related interaction between industry and commerce?such as online distribution?data interaction and service support.Due to the importance of the collaborative platform for industry and commerce,a large number of core business needs to be done through the collaborative platform.The business process based on the collaborative platform is becoming more and more complex,The operation of business processes processing in collaborative platform for industry and commerce put forward new requirements.For example,multiple instances of business process need to be executed in groups and approval a single process node requires collaborative processing.Therefore,The key technology in workflow such as the workflow model for handling instances and the scheduling mechanism are needed to be discussed in detail.In this paper,the idea of workflow instance model and scheduling research based on industrial and commercial collaborative platform have been put forward,Detailed analysis and research of workflow modeling and scheduling problems in the current business collaboration platform to build a workflow model and scheduling mechanism that can handle instances,and establish a time optimization model for handling instances scheduling.The detailed research contents are as follows:1)Build a workflow model for processing instances.According to the requirements of processing example combinations that put forward by enterprise collaboration platform for industry and commerce,on the basis of the traditional workflow model which increases the data operations information such as the processing area of the processing instance,the relationship between the example activities,The workflow model is built and the algorithm?BPW?is explored by the example model.Verify its accuracy.2)Construction the scheduling mechanism for processing examples.The mechanism includes related controller,queue of instance packets include input and output,control packet scheduling algorithm,which solves the problem of grouping multiple activity instances generated by the same type of business process.On the basis of this mechanism,a control engine scheme of instance packet scheduling is established,which accords with the ECA rules,so that the grouping of the instances can automatically complete the concurrency,split and other processing operations of the group instance under controlled condition.3)On the basis of scheduling mechanism of handling instance,A time optimization model D_X,Y| 1 | T_minis established to deal with the combined scheduling of instances.And an algorithm SAPSO-T is proposed to solve the model.examples of group activity instances generated by SAPSO-T,conduct implicit encoding select on the order,determining a selection sequence for the active instance,decoded the selected sequence on the active instance,combined with the control engine scheme of packet scheduling,got the active instance execution sequence.Compared with other algorithms,SAPSO-T is superior in time performance and solution quality.
